APPLIANCE FOR RAISING- SOLID BODIES.

To all i12/loin 'it may concern:

lie it known that l", FRANZ BEDUW, Sub.

it appertains to make and use the saine.

rl"lie present invention relates to improvements in elevating iiechanism or devices of that character in which by the action of a suitable body of compressed air admitted into aconduit or discharge pipe a stream of water. and solid materials can be withdrawn from a pit or receptacle in which they have been collected.

In the handling or transportation of solid granular' or fragmentary materials, for eX- ample,-gravel, sand, mineral, coal, coke, etc., it is customary to create a stream of water into which the materialslto vbe moved are clisclmi'ged and to collect suoli mixed water and solid imiterials in pits or tanks into which extend the intake endsof elevators of the character above referred to.

its commonly7 constructed,considerable inconvenience is experienced by reason of the I fact that it is often impossible to so regulate the admission and withdrawal of mate rial from suoli a pit or receptacle that there will not be an accumulation of the solid material of suoli an amount as to choke the intake end of the elevator conduit and frequently vhe entire apparatus is rendered inoperative by such an accumulation.

The object of the present invention is to provide a construction by which such accidental stoppage of the elevator devices is rendered impossible.

in the accompanying drawing there is illustrated one embodiment of the invention, the pit or receptacle and a portion of the elevator tubes being shown in vertical section.

As shown the water and solid material are collected in a suitable pit or receptacle, the interior of which is divided into two com partinents by a vertically arranged partition, the lower end of which is some distance above the floor or bottom offthe receptacle.

i The elevating devices, which extend into that coirpartiiient of the pit or receptacle which is., separated from the inlet thereto by the I 1 a vertical partition, comprise a relatively fixed or stationary tube a supported by suitable means at the upper end of the receptacle and provided with a laterally extending discharge branch I), and an intake tubular section o, which is telescopically connected with the section a and extends vertically within the pit or receptacle having its lower open end extending below the lower edge of the partition in said receptacle. Within the sections afc, of the elevator tube is arranged a pipe or conduit Z adapted to be connected by a flexible coupling g with means for supplyving air under pressure. Said air conduit is connected with and forms the support for the lower intake section c of the elevator tube and the discharge openings from said pipe d are at the lower end thereof adjacent the inlet to the elevator tube.

By means of a counterbalance weight f connected with the air conduit d, by a cablee, the intake'section c of the elevator is maintained at any desired. adjustment and by this means the height of the lower end of said tube section from the bottom of the tank or receptacle can be varied as desired.

lt will be understood that in operation compressed air discharged into the lower portion of the elevator tube will create an upward current therein, causing a stream of water and solid material to flow outward from the tank or receptacle through the discharge pipe l). ln event that there Iis an increase in the volume of thel stream .of water and material flowing into the receptacle suf- .ficiently to cause an undesirable accumulation of the solid 4particles in the bottom of the pit, the intake section of the elevator is readily raised and if desired such section canbe lowered farther into the pit.

lt will then be seen that the present invention provides an apparatus of the type and character referred to in which clogging or stopping of the elevator by reason of accumulation of solid material in the colle`c tion pit or receptacle is readily prevented.

It has heretofore been proposed to make the suction pipes or tubes of dredges from a' plurality of sections telescopically connected so would accommodate itself to the unevenness of the surface on which it rests or over which it is moved in use. Also in such dredges it `lias been proposed to direct a stream of water int-o the solid matter to be dredged for the purpose of loosening it and permitting it to be carried upward through that the lowest or bottom section.

e suction. pipe. Devices ot this character, however, ere quite diitferent leoni the subject oi" the present invention which., as hereinbeore noted, is designed particularly tor the handling ot suoli materiel send, coef., etc., which luis been. collected in a pit or receptacle into which it is :erried by a stream of Water. Such pits or receptacles are necessarily of relatively restricted area, und for reasons pointed out lieifeinbetore, it is very importent in this particular ort to be able to adjust the inward end of the elevating mechanism employed 'tor Carrying the grenuliir materielv from the pit.

Having thus described the invention what is claimed is:

l. ln :in apparatus ot the character describi-zd7 the coinbination with e, pit or rel Aceptaiele tor waiter und granular or inentery solid niateriah of an elevator com prising n sectional tube that extends into the receptacle, the lower intake section of seid tube bein@ teleseopieally connected with the section above it, o conduit extei'iding into and connected with the 'intake section oLt the tube for supplying1 air under pressureto seid .intake section, and e eounterbalence connected with seid conduit.

2. .ln en apparatus ot the character described, the combination pit or receptfiele for Weiter and grunuier or tragnientnry solid materiel, which receptacle is divided int-o two compartments by o verticeily arranged partition, the tower edge ot ,Lise

which is out ot Contact 'with the bottoni ot the receptacle, of e' discharge conduit eX tending into Vthe compartment of said receptacle which is separated troni the inlet thereto by seid partition, the lower end ot seid conduit being teleseopieelly supported and adapted to extend below the lower edge of said partition, und a conduit for discharging air under pressure into said discharge pipe adjacent the lower intake end thereof, substantiellyvas und for the purpose a described.

In an apparatus ot the character de scribed, the combination ot e pit or receptacle for water and granular or fragmentary solid material, which receptacle is divided into two compartments by n vertically or, ranged partition, the lower edge ot which is out ot Contact with the bottoni ot the receptacle, an elevator comprising a sectional tube that extends into the compartment ot seid receptacle which is separated :from the inlet thereto by seid pertition, the lower seeA tion of said tube being telescopically supported, and a conduit for discharging gas under pressure into said discharge pipe, substantially es and for the purpose described.
